I needed additional power supply for stuff that I do, and so after Mike’s review I bought Manson NSP-3630 which is exactly the same power supply as Tenma 72-8345, made by the same OEM(Original Equipment Manufacturer) – Manson.

I can’t add much more to what Mike said in his review, but if you want to see high-res photos of internals of this power supply – you’re in the right place.

Recently I needed some sort of probe to reliably stick onto a tiny .5mm pitch IC pins. My scope probe was a bit unwieldy for that. Not sharp enough either. And so I came up with this probe from a tiny insulin syringe. It is extremely sharp, so it’s really easy to pierce through oxidation coating or even through a solder mask.

This time I’ve got my hands on a very cheap motorcycle alarm with remote start capability. Here I will show you why you don’t ever want to buy a cheap alarm for your car/motorcycle and also will give you explanation on what makes it tick.

Mean Well it’s a Taiwanese manufacturer of power supplies. They offer a very broad range of switching power supplies ranging from cheap and simple models to more sophisticated models with lots of features and good component base. Here I’ll be taking apart their bottom of the range NES-15-12 (datasheet) 15 watts, 12 volts single output power supply.

Sometimes selecting a switching mode power supply for your project is no easy task, but information provided here would get you started. In this article I will tell you about most important things you need to know about switching mode power supplies (SMPS) (or just Switching Power Supplies – SPS).

Well, the thing is – now you can easily buy DC-DC converter chips for less than $0.2 in relatively small quantities. And because of that, and because different voltages required by microcontrollers and other chips – you can find yourself putting two or even more DC-DC converters on a single board.
